Problem

A particle in SHM moves from x=+3 cmx=+3\,\text{cm} to x=+1 cmx=+1\,\text{cm}. What are the signs of (i) work done by the restoring force and (ii) change in potential energy during this motion? a) Work −-,   ΔU  +\;\Delta U\;+ b) Work ++,   ΔU  +\;\Delta U\;+ c) Work ++,   ΔU  −\;\Delta U\;- d) Work −-,   ΔU  −\;\Delta U\;-
